代碼如下，它是go-libp2p的官方演示。我沒有遇到任何其他引用或未定義的錯誤 // if a remote peer has been passed on the command line, connect to it // and send it 5 ping messages, otherwise wait for a signal to stop if len(os.Args) > 1 { addr, err := multiaddr.NewMultiaddr(os.Args[1]) if err != nil { panic(err) } peer, err := peerstore.AddrInfoFromP2pAddr(addr) if err != nil { panic(err) } if err := node.Connect(ctx, *peer); err != nil { panic(err) } fmt.Println("sending 5 ping messages to", addr)導入如下：import ( "fmt" "os" "os/signal" "syscall" "github.com/libp2p/go-libp2p" peerstore "github.com/libp2p/go-libp2p-core/peer" "github.com/libp2p/go-libp2p/p2p/protocol/ping" multiaddr "github.com/multiformats/go-multiaddr")

// create context
ctx:=context.Background()
// if a remote peer has been passed on the command line, connect to it
// and send it 5 ping messages, otherwise wait for a signal to stop
if len(os.Args) > 1 {
addr, err := multiaddr.NewMultiaddr(os.Args[1])
if err != nil {
panic(err)
}
peer, err := peerstore.AddrInfoFromP2pAddr(addr)
if err != nil {
panic(err)
}
if err := node.Connect(ctx, *peer); err != nil {
panic(err)
}
fmt.Println("sending 5 ping messages to", addr)
